Planeturex App

Planeturex frames planet-building as a continuous feedback loop rather than a one-time creative act. You set parameters — orbital distance, star type, atmospheric gas ratios, eccentricity, planetary structure — and the system immediately recalculates temperature, radiation levels, and water stability. Nudge CO2 upward and watch the greenhouse effect climb; pull the orbit outward and surface water freezes solid. Nothing is consequence-free.

What You're Actually Adjusting

• Orbit & Star: Choose between a red dwarf, sun-like star, or blue giant, then dial in distance (in AU) and orbital eccentricity. Stellar flux and seasonal swing are tracked as dependent outputs.
• Atmosphere: Slide CO2, oxygen, and nitrogen levels individually or pick from presets — Earth-like, thin nitrogen, CO2-rich, or vacuum. A live planet preview updates temperature and a life score in real time.
• Structure & Water: Separate editor tabs handle planetary structure and water state, rounding out the four-variable system.
• Long-term simulation: Run extended projections to test whether your configuration stays stable over geological time rather than just at the moment of creation.

Progression and Challenges

The app tracks progress through an XP and milestone system — completing a planet creation step awards points, and a user rank (such as "Architect" at level 3) reflects cumulative engagement. Constrained challenge modes push you to hit specific habitability targets under restricted conditions, which forces genuine understanding of how each variable interacts rather than random trial and error. You can also save and compare multiple planet builds side by side to isolate what actually shifts the life score.

The life score topping out at 100 and the step-by-step wizard structure give the app an approachable shape, but veteran users may find the parameter ceiling limits how extreme or exotic their configurations can become.

Interface and Feel

The visual language leans into deep blues, golden yellows, and bright orange — the same palette that shows up in space-themed and deep-water environments alike. Sliders are large and clearly labeled with numerical readouts in scientific units (°C, atm, AU, g), and preset buttons offer shortcuts when you want to explore a known baseline quickly. The atmosphere builder uses a segmented progress bar across seven steps, so you always know where you are in the creation flow. Metric and imperial unit switching is available in settings. The color-coded gas sliders — purple for CO2, green for oxygen, yellow-orange for nitrogen — make the atmosphere screen particularly easy to scan at a glance, which shares a certain visual rhythm with games that use color-coded reels and symbols to communicate state instantly. In both cases, reading the board is half the skill.
